With our range of unique products and building systems, Lowfield Timber Frames Ltd are able to offer numerous product choices and specifications to achieve the requirements of either Building Regulations, The Code For Sustainable Homes, or even Passivhaus Standards.

Our Timber Frame and SIP systems can be modified to achieve u values as low as 0.10 W/m2k with excellent levels of air permeability. All materials supplied by LTF are responsibily sourced. We have a PEFC chain of custody in place to prove this.

A brief summary of material and system options are listed below however we are also developing hybrid systems all of the time.
